2022-02-15 11:32:16 +0100 <geekosaur> this has been a thing ever since perl started recommending installing directly over the package manager. couple decades ago
2022-02-15 11:35:27 +0100 <unknownbeing[m]> This has really made me aware that when getting into a new language, it's good to make sure that it has a solid ecosystem around it
2022-02-15 11:35:40 +0100 <unknownbeing[m]> Like python, C and many others
2022-02-15 11:36:02 +0100 <unknownbeing[m]> Even Lisp seems to have a pretty decent ecosystem
2022-02-15 11:40:01 +0100 <Solid> haskell's ecosystem is pretty decent in my book
2022-02-15 11:40:20 +0100 <Solid> just don't trust what package maintainers say or do :>
2022-02-15 11:49:55 +0100 <geekosaur> remember that a package maintainer's first priority is making packaging easier and fitting it into their package ecosystem
2022-02-15 11:50:09 +0100 <geekosaur> not what makes life easier for users of that ecosystem

2022-02-15 12:14:13 +0100 <geekosaur> duplicating largeish chunks of my existing OS is not an option on this small machine, and paving it over and installing nixos isn't either

2022-02-15 12:29:24 +0100 <Profpatsch> I wonder how much of a low-hanging fruit these are, since gzipped GHC is like 200MB and extracted GHC is 2GB
2022-02-15 12:29:42 +0100 <Profpatsch> So it’s only about 10% information
2022-02-15 12:30:08 +0100 <Profpatsch> otoh modern file systems are starting to have on-the-fly compression, so who knows if that will be relevant in 10 years
2022-02-15 12:32:56 +0100 <Solid> Profpatsch: nix the package manager is also shipping old versions of xmonad (because stackage) right now so... the only choice you have there is to install from source as well :>
2022-02-15 12:33:53 +0100 <Solid> (granted, there is a flake, but I still fail to see the utility of that over just issuing `stack build` even on nixos, especially because using local versions of xmonad and xmonad-contrib to build one's config seems non-trivial with the former)
2022-02-15 12:37:37 +0100 <liskin> Profpatsch: I still keep hearing horror stories of unrecoverable errors with btrfs :-/
2022-02-15 12:38:13 +0100 <liskin> almost started thinking about switching on the next opportunity (laptop/ssd replacement), but I'd like to have like a year or two without anyone around me having an issue with it
2022-02-15 12:39:01 +0100 <liskin> I'd love copy on write and compression and subvolumes though

2022-02-15 15:08:52 +0100 <geekosaur> main reason linux didn't adopt it is they want that oh so pure GPL licensing thing, but ZFS is BSD licensed
2022-02-15 15:09:51 +0100 <geekosaur> or at least BSD compatible; I haven't checked details

2022-02-15 15:55:38 +0100 <Benzi-Junior> Hey, I have a possibly ambitious (read, foolhardy) idea but was wondering if someone had done something like it before, is it possible to dedicate a workspace to a VM
2022-02-15 15:57:24 +0100 <geekosaur> in what sense?
2022-02-15 16:00:07 +0100 <geekosaur> we have TopicSpaces, for example
2022-02-15 16:01:33 +0100 <Benzi-Junior> so I haven't really thought this all the way through, but something like, when Xmonad starts one of the workspaces has virt-viewer as its base window,
2022-02-15 16:05:56 +0100 <Benzi-Junior> I haven't fully thought about how I want this to behave when it comes to controling inputs, and there may be an obvious reason for this being a terrible idea
2022-02-15 16:06:28 +0100 <Benzi-Junior> because odds are I'm going to want to be runnig xmonad on the VM as well
2022-02-15 16:13:00 +0100 <liskin> what works for me is just using fullscreen in virt-manager and then moving the mouse into the top minipanel whenever I need to press the keybinding to move to another desktop
2022-02-15 16:13:16 +0100 <liskin> (moving the mouse releases the keyboard grab, iirc)

2022-02-15 16:16:01 +0100 <geekosaur> I think you need to come back when you have a better idea of what you want. So far it just sounds like https://hackage.haskell.org/package/xmonad-contrib-0.17.0/docs/XMonad-Util-SpawnOnce.html#v:spawnO… (note that you need manageSpawn from XMonad.Actions.SpawnOn; this documentation oversight is fixed in git)
2022-02-15 16:20:43 +0100 <geekosaur> when I was running on a machine with enough oomph to run vmware workstation, moving the mouse into the menubar was enough to release the grab. or even into the border, except I usually had the border disabled on that window
2022-02-15 16:26:44 +0100 <Benzi-Junior> I think TopicSpaces might be pretty much what I'm looking for
2022-02-15 16:30:06 +0100 <geekosaur> I think there's also an alternative to TopicSpaces these days? need to dig more
2022-02-15 16:30:25 +0100 <Solid> there is, but I don't think it's as good
